So here is the situation. My wife has a 1 ghz ibook G4. The other day, her computer started to have kernel panics. Before it would happen, there would be a Mac OS X error message when she booted up the computer....what exactly it was I am not sure. Anyways, so I ran the apple hardware test and everything passed. I had already backed up all of her data, so I decided to do a clean install of OS X.4. So I go ahead and start the install. It goes through the first disc, but before it even asks me for the 2nd disc to install, it says it needs to restart. So I hit restart, and now the computer is not responding, with the startup disc stuck in the drive. If I press and hold the power button, the fan will turn on and it will make the startup sound, but nothing comes on the screen. It will eventually just shut off. It also will not start in target disc mode. If I press the power button long enough, it will make some sort of whistling sound and the sleep button will flash rapidly for a few seconds, but nothing happens. What can I do?
